groups and owners with ftp

Question

When a user "U" who is part of group "G" uploads a new file to the server with ftp , the permissions are set as U:U instead of U:G . I know the user is also part of his own group called "U" but how do I have them upload a file with the group "G". I don't see anyhthing in any FTP software. Thanks

Generally you do this when you want all files in a directory to be owned by a certain group. To make this happen set the SETGID bit on the directory chmod g+s. Then any file created in that directory will belong to the group that is associated ith the parent directory.
